CHARLES PRATT, OF NEV YORK, N. Y.

IMPROVEMENT 1N OIL-CAMS.I

Speclcation forming part of Letters Patent No. bbg, dated November 16,1869.

To @ZZ whom it may concern,.-

Be it known that I, CHAELEs Prea'rnlof the city, county, and State of New York, have invented certain new and useful Improvements in Oil-Cans; and I hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings.

j The object of the present invention is to form in a sheet-metal can and in one piece with the can a nozzle for the reception of the cork or stopper, said nozzle being so shaped as to present no sharp edges whichlwill cut or injure the stopper or prevent its rm insertion into the can, and being constructed as hereinafter described; and its further object is to so construct the nozzle that when the soft-metal cap which is soldered over it is cut away a suitable opening will be left,without sharp or jagged edges, in which the cork can be received and firmly held.

In the drawings, Figure 1 represents a perspective view of an oil-can, A, in the top of which is formed my sunk nozzle a from the same metal of which the top is composed, the said nozzle being so shaped as to receive and hold firmly the cork or stopper b, which in this instance is constructed in accordance with the invention described and claimed in Letters Patent issued to me as assignee of Conrad Seiniel on the 25th October, 1869. Fig. 2 is a view of that portion of the can in which the nozzle is to be formed, and is intended to represent the nozzle in one of its stages of formationthat is to say', after the metal has been stamped or cut out and slit and before it has been pressed by dies into its ultimate shape. Fig. 3 represents the same piece of metal after it has been pressed so as to form the completed nozzle. Fig. 4 is a transverse cent-ral section through the nozzle shown in Fig. 3. Fig. 5 is a top View of the soft-metal cap, around which a small shoulder, c, is formed, in accordance 'with the invention described in Letters Patent No. 89,167, granted to ine April 20, 1869. Fig. 6 is a transverse section of the cap and nozzle, showing the relative positions of the two, which are such that when the cap is cut away, by following around the shoulder c with a knife, the nozzle will be completely uncovered, and there willbe no sharp edge to interfere withor injure the stopper. Any other suitable soft metal cap can, however, be employed in lieu of that which is herein shown, in order to illustrate the manner in which my invention may be carried into effect.

I rst take the sheet of` tin which is to forni the top or other part of the can in which the nozzle is to be made, and stamp it with dies or other suitable means, so as to form the hole and radial slits or perforations, as seen in Fig. 2. Then, by means of dies, the metal is pressed so as to bend in the required direction so much of the tin as is needed to form the nozzle,which will vassume the shape shown in Fig. S-that is to say, it will have atapering form, the widest I part being at the point Where the cork or stopper first enters, and at this point the edge of the nozzle will be rounded and smooth, so as to readily admit the cork,which will not be cut or injured in any way. The nozzle can be thus made either upon the outside or inside of the can; but I much prefer its arrangement in the latter position, for the can will take much-less room in packing,while, if it is desired to empty the can, the cuts or slits in the nozzle will allow the fluid to run out freely, even if no special stopper be used. rlhe nozzle is, liowever, designed more especially to be used with the vent-stopper shown in Fig. 1, and above referred to. Their combined use with the can will give a good, cheap contrivance for holding the i'luid, and also for removing it from the can or vessel. Around the upper end of the nozzle is formed a groove, in which the edge of the soft-metal cap is held by solder. 'Ihe relative positions of the shoulder of the cap and that 'when the cap is cut away the nozzle will be left perfectly free and unobstructed,with no sharp edges which will injure or prevent the entrance of the stopper. 'Ihe advantage of the arrangement will be readily appreciated. The cap closes the nozzle and admits of the can being safely packed and transported, and then, when the oil is required for use, all that is needed is to cut away the cap, expose the nozzle, and insert the ventstopper,which fits the vessel, to serve as an ordinary oil-can for household and other uses.

The evident economy of material and labor nozzle from the same piece of sheet metal as the can-top gives the invention much of its the rounded upper end of the nozzle are such? which results from this mode of forming the 2 eene@ practical Value,Wl1ile the manner of combining the various parts and adapting them for use with the can is of great advantage, and produces an article much superior to ordinary vessels employed for like purposes.

Having now described niyinvention and the manner in which the same is or may he Carried into effeet,what I elaiin, and desi-re to secure by Letters Patent, is-

l. The Construction of nozzles -for oil-cans, in the manner herein shown and set forth, the sanie being formed in one piece with the top 0f the can by punching and slitting the metal and then bending and shaping the parts, as herein shown and set forth.
